Joinning don't pass after first roll

I know you can join the "pass" bet after the roll, but it is not recommended because the first roll is "good" for the pass bet.
But the first roll is not good for the don't pass bet, because it is almost the opposite.
Is there any rule against joining the "don't pass" after the first roll? I did not see anyone doing so, but on the craps page in the wizard of odds site I didn't find rule against it. It should be an huge ev+ if allowed...

Not allowed but I know someone who thinks it's hilarious and does it often. MustangSally claims you can take down your pass line bet in Australia after the come out. Anything's possible in Australia since they live upside-down.

It's not allowed.
If the bet is made after the come-out roll, it considered/converted to a Lay bet.

That makes sense but I've never seen a dealer actually do that. Everytime I see someone get caught trying this the dealer just gets annoyed and pushes their cheques back. If the dice are out they call "no action". I would personally move it to the DC. The craps layouts in Lake Tahoe are interesting (besides barring the two instead of twelve): Every don't bet travels behind a number making a late DP impossible.

This is a common shot-taking maneuver on the part of some crap players.

The late don't pass bet may be called no action, or may receive a "LAY" lammer on it, or is moved behind the number as a DC lay bet also with a lay lammer on it. If an early don't bet, moving it up behind a number as a flat don't come point is a very good game protection action.

For the same reason that you can take down a DP bet or create/increase a pass bet, but can't do the opposite: the former are bad player options therefore allowed, while the latter are a player advantage therefore not allowed.

Not in Sydney:
"A win line {pass line} bet cannot be reduced, increased, or removed after the Point is established"
